Abstract
In a method for operating a steering system for a motor vehicle, a set point torque predefined value is fed to a servomotor as a function of a manual steering torque generated by the driver, in order to generate a motor actuating torque which is to be transmitted to the steered vehicle wheels. A hysteresis torque is taken into account in the set point torque predefined value in order to compensate for the friction in the steering system.
